Percutaneous nephrostomy is a procedure establishing a drainage tract into the upper urinary system by puncturing the kidney directly through the skin. The purpose of such drainage is to decompress the upper urinary passage caused as a result of supra or intra vesical obstruction resulting in increased pressure within the collecting system and ultimately renal parenchymal damage. It can be used as a conduit for diagnostic and therapeutic procedures to provide urinary diversion and improve renal functions. In our clinic was used disposable nephrostomy kit, containing the following: syringe, scalpel, needle puncture with mandrel nr.18G, guide, three dilators and the actual nephrostomy. It is simple, less time consuming, less traumatic and has excellent outcome.
